我正在使用HDP样本，我有一个血压传感器（http://www.andonline.com/medical/products/details.php?catname=&product_num=UA-767PBT-C）。我从中获取数据，但我不知道如何将其解析为人类可读的内容。
这是我到目前为止尝试过的事情：
while(fis.read(data) > -1) {
String value = null;
BigInteger bi = new BigInteger(data);
// for(byte b:data){
// value+=b;
// }
Log.d("read data binary", "the data "+bi.toString(2));
Log.d("read data decimal", "the data "+bi.toString());
Log.d("read data hexa", "the data "+bi.toString(16));
Log.d("read data pure", "the data "+data);
// Log.d("read data in for", "the data "+value);
我得到类似的东西：

任何人都有任何想法解析它吗？
PS：很抱歉从logcat中提取所有内容，但也许有人找到任何连接
答案 0 :(得分：0)
我找到了解决方案。我需要传感器发送的确切字节数+传感器发送信息的方式。
我会把解析数据的部分用于我的血压计。
